Abstract (en)

[origin: EP2196695A2] The spring has a damping unit (36) comprising an inner control casing rotatable about a middle longitudinal axis (11) with respect to an outer damping housing. The casing is rotatable into two end positions by fluid flowing between two partial housing chambers (17, 18) in two opposite rotational directions, respectively. An outer through-flow opening of the housing and an inner through-flow opening of the casing are brought into overlap each other. The damping unit dampens insertion movement of a piston rod into a housing (1) and dampens ejection movement of the rod from the housing.
